Explanation:

Answer 2

Answer :-

** Please consider attached for solution.

◾Question No. 6 :-

▪️Volume = 426.2 cm³ or 0.4262 lite

◾Question No. 7 :-

$\bold{No. \:of \:electrons = 4.215 \times 10^{23}}$

◾Question No. 8 :-

→ (a) = 4 moles

→(b) = 2 moles

→(c) = 10 moles

→ $\bold{ d = \dfrac{1}{3} \: moles}$

→ (e) = 0.1975 moles

→ (f) = 5.417 moles

◾Question No. 9 :-

→ $\bold{a = 17.93 \times 10^{-23}\: grams}$

→(b) = 28 grams

→(c) = 100 grams

→(d) = 0.19926 grams

**Ignore Solution attached for 9.(d) it's wrong as I have took mass of Carbon = 6

◾Solution for 9.(d)

→$10^{22} \: atoms\: of\: Carbon$

▪️No. of moles = $\dfrac{10^{22}}{6.022 \times 10^{23}}$

$= \dfrac{1}{6.022\times 10}$

▪️Now Mass

$= \dfrac{1}{6.022\times 10}\times 12$

$= \dfrac{1.2}{6.022}$

= 0.19926 grams

◾Question No. 10 :-

→ (i) = 11.2 liters

→ (ii) = 33.6 liters

→ (iii) = 37.2 liters

→ (iv) = 2.82074 liters

◾ Solution for 10.(iv)

→ 3.4 g of Ammonia($NH_3)$

→ Molar mass of Ammonia = 27

→ No of moles $= \dfrac{3.4}{27}$

→ volume of the gas = $\dfrac{3.4 \times 22.4}{27}$

→ Volume of gas = 2.82074 liters
